Objective To investigate the best extraction technology of total flavonoids from peony stamens and pistils. Methods The effect of solvents on the total flavonoids extraction rate was investigated by preliminary experiment. The extraction technology was further optimized by L9(34) orthogonal test. Results The result of preliminary experiment showed that alcohol was more applicable solvent. The best extraction technology was as follows:the raw material was extracted with 20 times of 80%alcohol for 30 min, under the ultrasonic frequency of 25 kHz. Conclusion The extraction technology is simple, accurate and reliable. The content of total flavonoids in peony stamens and pistils reached 18.85 mg/g.
